摘    要:以扩展的圣维南方程组和有限差分方程组为基础,对河网进行合理的编码,采用Preissmann法对圣维南方程组进行离散,采用河网矩阵标识法的三级解法编制河网非恒定流的计算程序求解各断面的水位Z和流量Q。

关 键 词:河网  水流模拟  计算程序  数值计算  有限差分方程组

Abstract:Based on the expanded Saint Venant equation and f inite difference equation, rational coding of river network is conducted. Preiss mann Method is adopted in discretion of the Saint-Venant equation. Computer pro gram is compiled by using three-level solution method of network matrix identif ication to solve the water level Z and discharge Q at different cross s ections.
Keywords:river network  node  coding  three-level solut ion
